9. A phlebotomist is preparing to perform venipuncture for blood collection from a 5-year-old patient. Which of the following needles should the phlebotomist use?
Answer: C
The phlebotomist should use a 23-gauge needle for the venipuncture.
Using a 23-gauge needle is appropriate for performing venipuncture on a 5-year-old patient, as it is thin enough to minimize discomfort while still allowing for adequate blood flow.
A) 16-gauge
A 16-gauge needle is far too large for a pediatric patient, especially a 5-year-old. Such a large gauge would cause significant pain and trauma during the venipuncture and is typically reserved for adult patients or situations requiring rapid blood transfusion.
B) 18-gauge
Similarly, an 18-gauge needle is also considered too large for young children. While it may be used in certain scenarios for older patients, it can lead to increased discomfort and potential complications in a pediatric patient.
C) 23-gauge
A 23-gauge needle is the correct choice as it is designed for pediatric use, offering a balance between being thin enough to reduce pain and thick enough to facilitate adequate blood collection without obstruction.
D) 27-gauge
A 27-gauge needle is too small for venipuncture in most cases, particularly for blood collection. While it may reduce discomfort even further, it is inadequate for drawing blood as it could lead to prolonged collection times and difficulty achieving venous access.
Conclusion
The 23-gauge needle is the best option for performing venipuncture on a 5-year-old, ensuring an efficient collection process with minimal discomfort. Other options either pose risks of excessive pain or are insufficient for adequate blood flow, emphasizing the importance of selecting the appropriate gauge for pediatric patients.
